No asthma, no parasites is a rare type of leukemia: chronic myeloid neoplasm with eosinophilia and abnormality of platelet-derived growth factor receptor alpha.

Chronic myeloid neoplasm with eosinophilia and abnormality of platelet-derived growth factor receptor alpha (PDGFRA), referred as chronic eosinophilic leukemia, is an extremely rare neoplasm where long-term prognosis is uncertain though a high grade of responsiveness to Imatinib has been reported. The mortality and morbidity associated with chronic eosinophilic leukemia is associated with the degree of tissue involvement, damage, or both at diagnosis. We discuss a case of a young male patient with past medical history of hypoglycemia that presented to the emergency room with a complaints of a sharp abdominal pain localized in the upper quadrants.

Current status of allogeneic hematopoietic stem cell transplantation for paroxysmal nocturnal hemoglobinuria.

Treatment of patients with paroxysmal nocturnal hemoglobinuria (PNH) has been traditionally empirical, primarily aiming at ameliorating symptoms or treating complications resulting from the disease. Novel therapies such as eculizumab result in stabilization of hemoglobin levels and improvement in quality of life, but does not cure PNH. Nonrandomized studies suggest that long-term remissions are achievable when using myeloablative or nonmyeloablative/reduced-intensity (NMT/RIC) allogeneic hematopoietic stem cell transplantation (HSCT) as treatment for PNH.
